I don't know where you are in Florida but in Avon Park there is Avery's Bus & Truck Sales. They have a good inventory that rotates often I have been there & the busses are negotiable! Here is a link to their site. http://www.usedbusandtrucks.com/
They have more busses than is shown on the site.
Hope this helps with your search!

Don;t know if you've found anything yet, but I posted a new thread up above. 1985 international 62 pass, 5 speed manual. Jet black, former PA Dept of Corrections bus for their SWAT or CERT team or something. Conversion started, probably 98 percent there, needs a new 12V pump for the clean loop and thats about it. Read the above post!
